Why has my old friend kept on delivered & is watching my stories?

I used to be friends with this girl in High school & she lives 7 mins away so we used sleep over a lot but we got distant due to her getting her first boyfriend & hanging out with him & her ex would tell me how she misses me every time & junior year she sat behind me in one class but i was shy. & we got into one argument & her mom died days after so I told her make her proud and stuff and she said thanks. so a few years past and i reached out to her and sent her an old video & i told her i hope she’s doing well & she said the same and aw old memories and said no hard feelings. & then i went into depth and said how much i miss her and how I don't know why i didn’t talk to her earlier and i’ve been wanted to & hope that we can talk again & now she has left me on delivered for a day & has been watching every story. like at least give me closure or just live me on read i’ll get the message lol :/
